OBJECTIVE To determine whether childhood antianaerobic antibiotic exposure is associated with the development of inflammatory bowel disease (IBD). METHODS This retrospective cohort study employed data from 464 UK ambulatory practices participating in The Health Improvement Network. All children with ≥ 2 years of follow-up from 1994 to 2009 were followed(More)
BACKGROUND AND OBJECTIVES Antimicrobials are frequently prescribed for acute respiratory tract infections (ARTI), although many are viral. We aimed to determine bacterial prevalence rates for 5 common childhood ARTI - acute otitis media (AOM), sinusitis, bronchitis, upper respiratory tract infection, and pharyngitis- and to compare these rates to nationally(More)
We examined the impact of the Pediatric Infectious Diseases Society/Infectious Diseases Society of America guidelines that recommend ampicillin or amoxicillin for children hospitalized with community-acquired pneumonia. Prescribing of ampicillin/amoxicillin increased following guideline publication, but remains low. Cephalosporin and macrolide prescribing(More)
Concomitant antibiotic use during treatment for Clostridium difficile infection (CDI) increases the risk of recurrence. Across a network of children's hospitals, 46% of patients treated for CDI received concomitant antibiotics for a median of 7 days. Concomitant antibiotic use was more common among patients with malignancies, and solid organ or bone marrow(More)
A state-wide pertussis outbreak occurred in Washington during the winter–spring months of 2012, concurrent with respiratory viral season. We compared performance characteristics of a laboratory-developed pertussis PCR (LD-PCR for Bordetella pertussis, Bordetella parapertussis, and Bordetella holmesii) and rapid multiplex PCR (RM-PCR) for respiratory viruses(More)
The objective of this study was to determine whether antibiotic exposure is associated with extended-spectrum-beta-lactamase- or AmpC-producing Escherichia coli or Klebsiella pneumoniae infections in children. We collected extended-spectrum-beta-lactamase- or AmpC-producing E. coli or K. pneumoniae isolates and same-species susceptible controls from(More)
BACKGROUND This study was designed to determine whether an automated hospital-based influenza vaccination screening program leveraging the electronic medical record (EMR) increases vaccination rates. METHODS We performed a retrospective cohort study of all children ≥6 months old admitted to medical, surgical, rehabilitation, or psychiatry services during(More)
